摘要：

In order to explore the potential targets of toxicity of β-ionone on the photosynthetic system of Microcystis aeruginosa, the polyphasic rise in chlorophyll a (Chl a) fluorescence transient and transcript expression for key genes in photosystem II (PSII) of M. aeruginosa NIES-843 were studied. The EC50 value of β-ionone on M. aeruginosa NIES-843 was found to be 21.23±1.87mg/L. It was shown that β-Ionone stress can lead to a decrease in pigment content of M. aeruginosa NIES-843 cells, and that carotenoids were more sensitive to β-ionone str...
